Figure 1.

Histogram and density curves for mean pulmonary artery pressure and pulmonary vascular resistance (n = 662). This plot shows the relative homogeneous distribution of mean pulmonary artery pressure (A) and pulmonary vascular resistance (B) among the patients included in this study and stratified by the type of heart failure. The curved line is a density curve (i.e. proportion of values in each range), while the histogram shows the counts of values in each range. The dashed lines intercept the median value of mean pulmonary artery pressure (A) and pulmonary vascular resistance (B) for each of the subgroup. HFpEF, heart failure with preserved ejection fraction; HFrEF, heart failure with reduced ejection fraction; PVR, pulmonary vascular resistance; mPAP, mean pulmonary artery pressure
